Audi Q8 4M — Wheel Fitment & Specs
Overview
The Audi Q8 is a mid-size luxury crossover SUV made by Audi that was launched in 2018. It is the flagship of the Audi SUV line, and is being produced at the Volkswagen Bratislava Plant in Slovakia on the Volkswagen Group MLB Evo platform. The Q8 shares its platform with other high-end models such as the Lamborghini Urus and Bentley Bentayga. Compared to the previous generation (Audi Q7), it features a more sloped roofline, making it slightly shorter but wider than the Q7, with less cargo space due to its coupe-like design. The interior includes advanced technology like three touch screens, an enlarged virtual cockpit, and haptic feedback for user inputs.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 8.5J–10.5J | ET0–ET34 |
As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
